Hard drives greater than 2TB may not work on existing operating systems

External USB, eSATA, Firewire, and internal hard drives over 2 TB's cannot be formatted on Windows 32-bit operating systems using the Master Boot Record (MBR) partitioning scheme. As a result, when you connect drives over 2 TB's, depending on which interface you are using to connect them to the computer, they may not be recognized at all. They may be only partially recognized showing 700+ GB, or they may be recognized but you can't access them. Other issues such as the system locking up or the computer not being able to boot may also occur.

This is not an internal or external hard drive issue. It is a 2TB volume limitation caused by the Master Boot Record (MBR) partitioning scheme that has long been used by Windows 32-bit operating systems such as Windows 2000 and XP.

In order to use a drive larger than 2 TB, you will need an operating system that can partition and format that drive. Windows 7, Vista, Windows XP (64-bit), Mac 10.4, Mac 10.5 and Mac 10.6 all have this capability through the GUID Partitioning Table (GPT). The GUID partitioning scheme has the ability to partition both internal and external drives far beyond 2 TB in size.

For more information on GUID partitioning please see:

For more information on MBR partition size limitations, please see:

How can I test my drive to see if it is defective?

A: If you are experiencing problems with your drive or would just like to test the driveís integrity, download and run the HGST Drive Fitness Test.

If possible, we recommend that you backup any important data before running the test. Run the quick test first. If you are experiencing problems, but receive the result 0x00 try running the Advanced Test option. When you have completed the test, please contact the Support Center with the results and our agents will be able to assist you on resolving the problem.

How do I make an exact copy my old hard drive and put in on the new hard drive?

A: There are several alternatives available depending on your hardware platform and operating environment.
PCs
Symantec Norton Ghost
Acronis True Image
Miray HDClone
Many laptops only have one internal drive bay. One solution is to mount the drive into an external enclosure and clone the drive. Apricorn and CMS both offer reasonably priced packages. Please visit the following sites for details:

EZ Upgrade Universal Hard Drive Upgrade Kit by Apricorn
CMS Data Transfer Kit for 2.5" Laptop Drive by CMS Products

The advantage of using an external enclosure is that you can use your original drive as additional storage once the cloning process is complete.
Mac
The most popular software is Carbon Copy Cloner by Mike Bombich:

How do I Defragment my hard drive in Windows?

Open My Computer (XP) or Computer (Vista/7) from your desktop or Start Menu. Right click on the drive you would like to Defragment and select Properties. Choose the Tools tab and then select Defragment Now.

How do I find the hard drive on my system?

In Windows, the drive should appear under My Computer as another hard drive shortly after being connected.

On a Mac, the drive should appear on your Desktop shortly after being connected.

If your drive does not appear in the appropriate location, please consult the Troubleshooting guide.

I added a new drive to my system, why have the drive letters changed?

External drives are not assigned a permanent letter by Windows. The next available letter will be assigned at drive connection or system startup. Based on the order the drives are detected by the computer this may cause a drive to be assigned a different letter than you are used to. If you would like to permanently assign a letter to a drive, this can be done in Disk Management. The steps below will guide you through setting a letter. Some screens may vary slightly depending on your version of Windows, but the steps are the same. You will need to be logged in as an administrator to complete this process.

  1. Right Click Computer/My Computer on your desktop or in the Start Menu and select Manage.

What is a true backup?

The most basic description of a backup is a copy of your files. This means having your files stored in at least two places. The original file remains on your computer and a copy is stored in another location, such as another computer, an external drive, CD/DVDs, or in an online backup. Anytime a file is stored in only one location it is at risk. Backups can be done by simply copying the files to a second place using drag/drop, copy/paste, or send to options. A more structured backup can be done using software specifically designed for that purpose. There are several types of backup software available. Many will do a ìdata copyî backup. A data copy entails just copying personal files like pictures, documents and music. Other programs will do a ìcomplete system backupî that includes all program and operating system files. This type of backup is frequently referred to as a clone, image, or disaster recovery.

There are benefits and drawbacks to each of the two backup types. A data backup takes less space and can be processed much more quickly. It also makes restore of individual files much easier. However, in the event of a system failure the OS and all programs will need to be reinstalled separately. The complete backup avoids the issues of reinstalling, but can reintroduce system problems that existed when the backup was created. Also, with a complete backup a complete restore is generally required. Individual files and folders cannot be accessed separately.

Backup programs copy files in two different ways. Most programs that backup only data do it with a simple copy, allowing direct access to the files from the backup without requiring a restore. The second method, which is generally used in a complete backup, is to archive the files. All files and folders are combined into a larger file(s). This file(s) can only be accessed using the restore function built into the backup software. The archive provides an extra layer of protection to the files, as they cannot be accidentally modified and are far better protected from viruses.

A “true backup” involves more than just copying the files. In this situation multiple revisions of a file are stored. This provides protection beyond simple hardware failure. In the event that a file is edited or corrupted and then backed up, access to a previous version is still possible. This type of backup can require a great deal of storage space, as a single file will be stored repeatedly.

Where can I find information on RoHS compliance and HGST drives?

A: HGST provides a web site specifically for RoHS/WEEE information:

RoHS/WEEE

Where can I purchase HGST hard disk drives?

A: You can find purchasing information and sales links in the Where to Buy section of our web site.

Where do I find drivers for my HGST drive?

A: All operating systems (OS) have hard disk drivers built into the OS by default. No additional drivers are required for the drive itself.

If you are being asked for drivers by the installation software or your drive is not detected during the OS installation, you may need to download the most current version of your controller or motherboard drivers. To obtain the most current version of your controller or motherboard drivers, please contact the manufacturer of your controller or motherboard or visit their web site for more information.
